Demographic responses to population recovery illustrated by 30 years of monitoring a once critically endangered parrot

open access: yesJournal of Applied Ecology, Volume 63, Issue 8, August 2026.
These findings highlight the dynamic nature of demographic processes throughout population recovery and emphasise the value of continued monitoring beyond apparent recovery to detect density‐dependent shifts in demographic rates of wildlife populations.

Rcapture: Loglinear Models for Capture-Recapture in R

open access: yesJournal of Statistical Software, 2007
This article introduces Rcapture, an R package for capture-recapture experiments. The data for analysis consists of the frequencies of the observable capture histories over the t capture occasions of the experiment. A capture history is a vector of zeros

Residual diagnostics for assessing closed population capture–recapture models

open access: yesMethods in Ecology and Evolution, Volume 17, Issue 8, Page 2277-2284, August 2026.
Abstract Capture–recapture models provide a statistical framework for estimating demographic parameters from incomplete observation data, where not all individuals in a population are detected during sampling. Assessing the fit of such models is crucial for reliable inference.

Abundancia de dos poblaciones de toninas (Tursiops truncatus) en el norte de Veracruz, México

open access: yesRevista Mexicana de Biodiversidad, 2011
En México no se conoce el tamaño de las poblaciones de la tonina (Tursiops truncatus) debido a su gran movilidad y al ocasional intercambio de individuos entre poblaciones.

Annual survival estimation of migratory songbirds confounded by incomplete breeding site-fidelity: study designs that may help [PDF]

open access: yesAnimal Biodiversity and Conservation, 2004
Many species of bird exhibit varying degrees of site–fidelity to the previous year’s territory or breeding area, a phenomenon we refer to as incomplete breeding site–fidelity. If the territory they occupy is located beyond the bounds of the study area or

The Jolly-Seber-Tag-Loss model with group heterogeneity

open access: yes, 1969
Mark-recapture experiments are performed to estimate population parameters such as survival probabilities. Animals are captured, tagged, released, and recaptured at subsequent time periods in order to obtain parameter information.

Age‐specific survival of reintroduced swift fox in Badlands National Park and surrounding lands

open access: yesWildlife Society Bulletin, 2016
In 2003, a reintroduction program was initiated at Badlands National Park (BNP), South Dakota, USA, with swift foxes (Vulpes velox) translocated from Colorado and Wyoming, USA, as part of a restoration effort to recover declining swift fox populations ...

Anthropogenic and Environmental Factors Influence Kentish Plover (Anarhynchus alexandrinus) Survival in a Conservation-Reliant Coastal Population

open access: yesBirds
Bird survival is influenced by both natural and anthropogenic factors, including weather conditions and oil spills. In this study, we examined the impact of a major oil spill (Prestige oil tanker) and climatic conditions (precipitation and wind) on ...
